+        This method should be called from format() by a formatter which
+        wants to make use of a formatted time. This method can be overridden
+        in formatters to provide for any specific requirement, but the
+        basic behaviour is as follows: if datefmt (a string) is specified,
+        it is used with time.strftime() to format the creation time of the
+        record. Otherwise, the ISO8601 format is used. The resulting
+        string is returned. This function uses a user-configurable function
+        to convert the creation time to a tuple. By default, time.localtime()
+        is used; to change this for a particular formatter instance, set the
+        'converter' attribute to a function with the same signature as
+        time.localtime() or time.gmtime(). To change it for all formatters,
+        for example if you want all logging times to be shown in GMT,
+        set the 'converter' attribute in the Formatter class.
